POWER-SAVING FUNCTIONS IN COMMUNICATIONS NETWORKS

摘要

A communications network using end-to-end tunnels, a control unit (7) is arranged to monitor the traffic load on at least two paths, determine a power saving traffic distribution if the total traffic on the at least first and second paths if traffic load does not exceed the capacity of both or all paths between the same end nodes. In said power saving distribution at least one of the first and second path is put in a standby mode in which it carries no traffic. Command means are arranged to redirect traffic according to said power saving traffic distribution and to order at least one network element or at least one link in the path or paths to be put in standby mode to enter into a power saving standby mode.
